gluon-status-page: show additional info

[rotanid]

inspired by #1402
related and maybe partly depending on #644
show the pretty names for additional data and hide the labels for unavailable fields

• site 21397ce678c32539247196135e3c30d914d5c592
• domain 21397ce678c32539247196135e3c30d914d5c592
• roles
• wifi channels
• bandwidth limit
• VPN type (active / fastd / l2tp / ...)
• batman version / babel ?
• nexthop #1878

Domain pretty names is pretty expensive right now. We get the value in nodeinfo.system.domain_code and have to look at all files in /lib/gluon/domains/*.json.
A package that does this is gluon-config-mode-domain-select but that's because it shows all pretty names anyway.

[rotanid]

showing the non-pretty names would still be an improvement ;)

Really? ffda_da_220_230 doesn't sound like anything I'd put on a status page.

[rotanid]

more than nothing, although not ideal.
judging from our experience, no one except people with deep technical knowledge uses the status page anyway...

I am preparing a patch for this in https://github.com/FreifunkChemnitz/gluon/tree/status-page-extension I will add a PR as soon as I am happy with it.

[mweinelt]

If traffic limits are in place it would be great to publish them on the status-page as well.

[rotanid]

added wifi channels, from #1727
